OH, color me intreged by this tread.
Infantry: High experiance, well trained soldiers who carry assualt rifles and Anti-Tank/Air missiles, and grenade launchers on the rifles. They will be trained for urban warfare, since that about the only time I even DEPLOY infantry in RTS games. They would also carry heavy body armor to keep themselves alive, and move by IFV or chopper.
Recon (land): My tactics ususally revovle around heavy recon before the attack, so I will include a recon unit, both land and air. Now, for landbased recon, I would want to have a 4 wheel-drive, humvee-esque vehicle, with high speed, decent armor, and enough firepower to cover itself and escape.
IFV: To move my infantry into and out of battle, and fight other infantry, I would want an IFV with an autocannon on it, as well as several machine guns and fireports so infantry can shoot out of the vehicle. It should also have light AT abilities to fight against other IFVs and hold its own against a lone tank.
Tank: A large, heavily armed and armored, but slow behemoth of a tank. It should have heavy cannons to destroy tanks with, anti-air missiles to defend from choppers and bombers, and while a machine gun to attack infantry is preferable, it is not nessesary. To avoid destruction, they will move in a pack of at least 15 tanks per unit. Think Mammoth tank from CnC:
Recon (air): It should be the same as the land recon, but more firepower, so that I can hit a target before it moves. For looks, think SR-71 Blackbird with missiles.
Chopper: The transport/attack chopper would hold room for a small squad of infantry in it, but its primary role will be in the form of attack. It will have enough armor to keep itself alive and escape anti-air fire, be armed with gatling guns and AT missiles.
Fighter/bomber: The plane will be able to switch roles at an airbase. It can go up with a load of AA missiles, or AGMs. They will carry a gatling gun to defend themselves in combat if they run out of missiles, and will have an automated rear-firing gatling gun. For looks, think Halo Longsword:
Super-unit: Ladies and Gentlemen, allow me to intraduce you to Kai. Heavyarms Kai:
This monster is 40 feet tall, has 2 70mm gatling guns instead of a right arm, and has 2 more 70mm gatling guns behind the blastshields on its chest. In addition, it has a pack of missiles on each leg, and one in each shoulder. If it gets into CQB, he has a giant gundanium knife to fight with. I dare anyone to stop this beast.
Hero: I offecially draft General Scott Michell, the hero of Ghost recon, to lead my forces to vicotry.
